Another IEP coming next Friday

We had an IEP in September, my request. January IEP requested by school because it was 1 year. Now IEP requested by me again. I do not know what is acceptable, what can I request? His current behavioral "plan" is if he feels an outburst coming on he is to leave the class and go to another room (which is supervised).
I don't want him to think he can just walk out of any situation he doesn't like, or feel like doing. This won't help him later in life.
I want him to be responsible for himself, now someone collects any missing work, helps him do it if he was not in class.
JUST found out from him that he only attends 30 minutes of English, then goes with an aide and just sits there the other 30 minutes. (doesn't like English teacher)
School wants to send him home when he disrupts class. According to many teachers, that means talking out of turn. i do not WANT him home. If we do not come get him he sits in the office or ISS (in school suspension) the entire day. He is not violent. Can be verbally abusive.
What can I ask for? I would like suggestions because I do not know what I CAN ask for.

It is VERY important that the request be sent to the school district via Certified Mail. I typically fax a copy of correspondence to speed up snail mail, HOWEVER, the letter must still be sent Certified Mail.

There are sample letters in the Special Education archives if you need them.

My letter would be formulated as follows:

Certified Mail No.______________
Fax No. (xxx) xxx-xxxx
